Hi I'm Stella Metsovas. And today we're going to talk about packing on that extra muscle and body building supplement facts. One of the top questions I'm often asked, do these supplements really work? And do they actually increase testosterone and muscle? Can I really gain seven pounds in one week? Actually seven pounds of muscle in one week. Is there truth in these supplements or could you just be wasting your money. The goal of all bodybuilding supplements is to naturally increase testosterone levels and boost lean muscle tissue by regulating glycogenesis. The most common supplements that have a research backed, time-tested evidence include creatine. Creatine is probably the top. Known to increase lean muscle tissue and muscle cell volume and more importantly to increase glycogen synthesis. The actual storage form of energy in the muscle. Whey proteins helps flood the body with protein and minerals essential for lean muscle gain. Branch chain amino acids or BCAAs contain three amino acids, leucine, isoleucine and valine. The body uses these amino acids for muscle recovery allowing you to prepare for your next workout. Glutamine is also another top pick because it helps in preserving muscle breakdown. It also helps to naturally stimulate growth hormone in the body. Truth is the most important factor of all though is your diet. Yes the foods you eat. I promise you.
